Natural selection of tools - You've made my day, first I was laughting, then i realize that on my desk is exactly the same situation when I repairing electronics, tools used very very rare lands on the floor when the desk ends ;) I like playing Your videos when im repairing things, even if cant watch, just to hear what You have to say Started from the oldest and watching every day for few hours Few tips from Your videos was very useful, keep it up, good work!

@wattage 5 лет назад

You have an incredibly challenging work environment, Sorin! The mic you normally use blocks out the background noise for us. But this time, we could hear what you face daily. You have to deal with so much noise and distraction every day. And you have so little space to work on the things. All this, and you're still able to work so efficiently and teach us along the way. Wow! You are a really talented and patient teacher. I'm sure the mic will be sorted in future vids. Thanks again for all your efforts!

@alexmihai22 5 лет назад

I really like the ambient noise, it's simply nice, itțs the vibration of that place.

@ingolf17 5 лет назад

A huge thanks for all your work and effort. Really glad you take the time to teach how to solve problems like this. Keep up the great work. Wish you the best :)

@shahmuhammadmuhammadi3550 5 лет назад

i am really addicted to your videos, i got too many things from your video thanks.. thats unique specially the way you describe the chips,faults,and other problems....

@costasmalovyk6583 6 лет назад

Great Job. Your videos helped me a lot to fix my motherboard. Even though I had the schematic was still finding it difficult to figure it out. Great help. Thank you.

@timothyokunola1518 4 года назад

your channel has finally become my Laptop reapair bible as well as my mobile phone repair bible.....your videos have been really insightful and also you have successfully helped my courage. the whole New year Holiday has really helped me to increase my knowledge in my chosen profession. thanks a lot sir Sorin)

@yuanho2883 6 лет назад

Great video! That was painful. Just do it your way, the way you like to do it. I like how you do it, quick, efficient, precise, smart, and the most important thing, it works! When you explain which mosfets to short and which ones not to short, that is enough. Do it your way, that is the best way. and Thanks!

@VibeStreamer 6 лет назад

Hi SORIN!!! Thanks for your time, your effort and above all your explantion, for now it's 100% accurate -at least with my level- but for your way of repairing I don't mind since you can fix the issue so don't waste time trying to do (default repairing) this is obvious, keep shining and as I already said you are inspiring and I became addicted to your channel too, have a nice day!!!!

It is easy to understand any subject like electronic or auto diagnosis, but trying to explain to others in words is tougher than most people thin when you are doing it on the fly without rehearsing before filming.

@bouazizrachid9682 6 лет назад

Thanks a lot, after removing the mosfet would it work if you only jump it with a wire like you did in many of your videos? if not way?, thanks

@zx8401ztv 6 лет назад

Hey we all have those days of forgetting stuff, you are not the only one :-). You still have a bit of a cold, you are not 100% yet. You may want to discribe the power channeling mosfets as "Gates", open or closed gates, for people that dont understand. Usually if the mosfet has a P junction, then the gate voltage is lower than the drain to switch on, and a N junction gate is higher than the drain, as far as i can remember, but mosfets are something i didnt learn much about lol. i could be wrong LOL

@electronicsrepairschool 6 лет назад

no, your right

@lesleymunro4964 6 лет назад

Actually It's the difference beween the gate and source (Vgs) which turns on a MOSFET. N channel, the voltage is positive beween the gate and source, P channel it is negative. This doesn't mean you need a negative voltage on the gate, only negative in relation to the source. In that circuit, the source is connected to 19V, the drain is the output to the rest of the laptop, and the gate would get pulled low to turn it on. I found a quick tutorial here which might make sense of it. www.baldengineer.com/p-channel-mosfet-tutorial-with-only-positive-voltages.html

@pollyannabutchers 5 лет назад

hi Sorin , had an LG G3 totally dead , last resort warmed entire phone up (on a hot radiator) hey presto back to life!!!! would never have tried this until i saw you do it with a samsung CHEERS!!!! (btw i only use the LG for a screen for my quadcopter..lol) also has a no read sim card issue, but thats another story...keep up the good work

@josejimenez-jc1kl 2 года назад

you'll always be the best💯

@ShaDoWxGFX 6 лет назад

I have a Toshiba Satellite laptop. My first mosfet reads 5V at the Gate. Should it be reading 19v? It is a P Channel Mosfet

Nice watch! My last company where i worked before the pandemic. 😊

@TeamP 2 года назад

Some charging ports can become damaged through constant wear. I have found on some DC/IN connectors that the central pin & the side rails can sometimes become loose or bent enough to not sustain a proper connection with the adapter end.

@4EVERGR 6 лет назад

Great video Sorin. When we put the charger cable on toshiba laptop and cable is not stable in the jack, do we need to replace the charging port or can be fixed some way?

@electronicsrepairschool 6 лет назад

well, depends of what kind of damage is there, if its cracked inside, you can fix it with hot glue

@nickdick9766 5 лет назад

At 23:40 you test a p-channel mosfet for short. You say that you have used your bench power supply. Can you explain the test you did ? The (-) of the power supply is applied to GND but where did you connect (+) ? How this test works ?

@RokasSondaras 6 лет назад

Amazing job you're doing here, I constantly watch you videos, and I'm so generous for your knowledge, please open a patreon and I will donate to you, because you make a difference in repair industry. EDIT: Please make a video on finding short on motherboard in deaph.

Hi im a newbie in electronics and only took online tutorial😅 here at youtube university especially on your channel, where can i get a parts replacement like a mosfet? Thank you in advance and more power to your channel god bless

@mahound9 6 лет назад

Oh jeez, I just did an overhaul on one of these, I think just slightly newer. Slick, when they have modern SSD and RAM.

@onuohakenneth1747 6 лет назад

Pls I have a HP envy 17 when I power it on it comes on and the caps lock blinks a white light 4 times then goes off. So I pull out a ram actually I tested both ram separately. One of the ram when inserted just blinks once and power off repeatedly.the other one blinks 4 times and powers off also repeatedly.pls how can I do this

@endrestory4345 5 лет назад

I like your dogdy way of learning elektroniks. Its wery useful for me, its like i hawe some nolage, but i'm not so god in matematiks. So i need the croul way of learning how it works. Beutiful way you learning away elektroninks on. Thanks from Norway

@georgekaramolegos5345 6 лет назад

Great job once again.What would you do though if still the laptop turns on all voltages are ok and still no display?i was given a same model a year ago and i still have not figured it out.Can you please make a video about how you can check ram sticks , cpu and gpu?Greetings from greece . Ps .i have a new moto now, IF YOU CAN SHORT THEN SHORT,IF NOT REPLACE !

@electronicsrepairschool 6 лет назад

Hi, is no way to check the ram if the screen is black, just replace and check again. I do have few video about coming on but no picture on the screen

@remus-gabrielangheloaia375 6 лет назад

Sorin, cei doi mosfeti sunt de regula de tip P chanel. unul e ous invers fata de celalalt. Daca chiar ai nevoie, cauta schematics pt hp 4510s si poti observa. Sunt si modele cu unul P si unul N, chiar si modele cu un singur mosfet P ch. Sau uita-te ce scrie pe spatele mosfetilor si vezi ca sunt la fel. Cauta apoi schematics pt ei pe net.
